Title: The Innovative Contributions of Eugene C. Heltemes
Introduction
Eugene C. Heltemes is a notable inventor based in White Bear Lake, Minnesota. He has made significant contributions to the field of electronic article surveillance systems, holding a total of seven patents. His work has advanced the technology used in security markers, enhancing their effectiveness and reliability.
Latest Patents
Among his latest patents is the "Dual status magnetic marker having magnetically biasable flux collectors." This innovative marker is designed for use in electronic article surveillance systems that operate with an alternating magnetic field. The marker features a magnetic responder element with a central switching portion and flux collectors on each end. These flux collectors concentrate the magnetic flux within the switching portion, ensuring that the flux density is sufficient to generate an appropriate response. The dual status capability is achieved by incorporating magnetizable keeper elements adjacent to the flux collectors. When these keeper elements are magnetized, they bias the flux collectors, inhibiting magnetization reversal in response to an interrogation field. This design prevents flux from the interrogation field from being concentrated in the switching portion of the responder element.
Another significant patent is the "Random-filament, multi-directionally responsive marker for use in electronic article surveillance systems." This magnetic marker is designed to provide a two-directional response. It consists of a substantially two-dimensional, sheet-like substrate with multiple metallic filaments randomly dispersed or adhered to it. These filaments are oriented to be substantially parallel to the plane of the substrate. Selected for their low coercive force and high permeability, the random orientation of the filaments allows certain filaments to intersect and magnetically couple with others. This configuration effectively collects and concentrates lines of flux associated with an applied field of an electronic article surveillance system.
